Let's divide 10463885 by 520
Our goal is to divide 10463885 by 520.

Moving on to step 1:
520 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 520

Let's proceed to step 2:
When dividing 10 by 520, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 520

Let's proceed to step 3:
520 goes into 104 0 times with a remainder of 104.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Include the next digit (6) from the dividend after 104, then repeat: 1046 / 520

On to step 4:
When dividing 1046 by 520, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1040 from 1046 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 520

Moving on to step 5:
The number 520 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 63 to get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 520

On to step 6:
When dividing 638 by 520, we get 1 with a remainder of 118.
The next digit of our result is 1. 
Result so far: 201.0
If we subtract 520 from 638, we get 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 520

Step 7:
The number 520 fits into 1188 2 times, leaving a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 2012.0
Subtract 1040 from 1188 to get 148.
Fetch the next digit (5) from the dividend, attach it to 148 and continue: 1485 / 520

On to step 8:
The number 520 fits into 1485 2 times, leaving a remainder of 445.
Record the quotient 2 as the next digit in the result. 
Result so far: 20122.0
Subtracting 1040 from 1485 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 9:
4450 divided by 520 is 8 with a remainder of 290.
Use 8 as the next digit of our solution. 
Result so far: 20122.8
Subtracting 4160 from 4450 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
When dividing 2900 by 520, we get 5 with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 20122.85
The remainder is 300 after subtracting 2600 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
3000 divided by 520 is 5 with a remainder of 400.
The next digit of our result is 5. 
Result so far: 20122.855
Subtracting 2600 from 3000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 20122.855 with a remainder of 0.04.
